Not only that. This is a wild, delinquent monk seal pup named Manu'iwa.

It's grown up past its mother's control which is now prompting the Hawaii Department of Land and Natural Resources (DLNR) to issue a warning to locals and tourists who might encounter it.

"There was real concern that the seal pup might swallow the knife," the wildlife officer who filmed the video said.

"It’s a reminder to all of us to properly dispose of our trash and not to leave it on Hawaii’s beaches or in the ocean."

The wildlife officer was eventually able to retrieve the knife after Manu'iwa dropped it.

Director of the local sea lion hospital, Claire Simeone, said people should be very careful around young seals.

"Monk seal pups of Manuʻiwa’s age are essentially toddler-like in their behavior, and aren’t necessarily aware of the dangers of the objects they find in their environment," Dr Simeone told West Hawaii Today.

People are instructed the best method for an encounter with a baby seal is to be boring and ignore them, not engaging with it.

And in all fairness, everybody looks boring when they are next to a baby seal with a knife in their mouth.
